In this embodiment, an example in which the safety information of disaster victims is collected as an example of information from an appropriate person who is qualified to provide information is described, but the present invention is not limited to this.

  FIG. 1 is a configuration diagram of an example of an information collection system of the present invention. In the information collection system of FIG. 1, an information collection apparatus 1 and a digital broadcast receiver 5 are connected via a network 3 such as the Internet network. The digital broadcast receiver 5 can receive a data broadcast and can use an interactive service.

  The information collection device 1 includes a safety registration content generation device 10, a program DB 11, a B-CAS number DB 12, a data broadcasting device 13, and an authentication registration broadcasting device 14. In the information collection system of FIG. 1, the information collection device 1 including one housing is described as an example, but the safety registration content generation device 10, the program DB 11, the B-CAS number DB 12, the data broadcasting device 13, A part or all of the authentication registration broadcasting device 14 may be installed in separate housings.

  The safety registration content generation device 10 displays the program body (anpi.bml) of the safety registration content read from the program DB 11 and the B-CAS number to be displayed on the safety information registration screen 7 read from the B-CAS number DB 12. The safety registration content is created with the file (bcas.btb).

  The program body of the safety registration content is described in, for example, a broadcast markup language (BML). BML is information obtained by encoding information for arranging and controlling various materials (mono media) such as still image data, text data, and additional audio. It is assumed that the B-CAS number of the digital broadcast receiver 5 installed in the refuge 4 is registered in the B-CAS number DB 12 as the B-CAS number to be displayed on the safety information registration screen 7.

  The safety registration content created by the safety registration content generation device 10 is transmitted to the data broadcasting device 13. The data broadcasting device 13 broadcasts the safety registration content as data broadcasting content. Data broadcasting in digital broadcasting is described in detail in, for example, “ARIB STD-B24”.

  The digital broadcast receiver 5 installed in the evacuation center 4 receives the data broadcast from the data broadcast device 13 via the data broadcast network 2 and displays the safety information registration screen 7 on the display device 6. At this time, in order to suppress the occurrence of mischief, the digital broadcast receiver 5 installed in the refuge 4 can display the safety information registration screen 7 in the information collection system of FIG. The receiver 5 is prevented from displaying the safety information registration screen 7.

  As a mechanism for enabling the digital broadcast receiver 5 installed in the evacuation center 4 to display the safety information registration screen 7 and preventing the digital broadcast receiver 5 installed other than the refuge 4 from displaying the safety information registration screen 7. For example, this can be realized by using a B-CAS number that can uniquely identify the digital broadcast receiver 5.

  The B-CAS number can be obtained from a B-CAS card inserted in the digital broadcast receiver 5. Prior to data broadcasting, in the information collecting system of FIG. 1, the B-CAS number of the digital broadcasting receiver 5 installed in the refuge 4 is grasped on the information collecting apparatus 1 side.

  In the information collection system of FIG. 1, for example, the B-CAS number of the digital broadcast receiver 5 that can display the safety information registration screen 7 is broadcast as a data broadcast together with the program body of the safety registration content, so that the digital installed in the refuge 4 The safety information registration screen 7 can be displayed on the broadcast receiver 5, and the digital broadcast receiver 5 installed outside the refuge 4 can be prevented from displaying the safety information registration screen 7.

  The victim can register the safety information from the safety information registration screen 7 displayed on the display device 6 by using the information input function of the digital broadcast receiver 5. The digital broadcast receiver 5 uses the communication function of its own device, and transmits the registered safety information and its own B-CAS number to the authentication registration broadcasting device 14 of the information collecting device 1 via the network 3.

  The authentication registration broadcasting device 14 uses the received B-CAS number of the digital broadcast receiver 5 in order to eliminate the risk of registering safety information by impersonating the victim due to theft of the B-CAS card. As described later, the validity of the digital broadcast receiver 5 is authenticated, and the safety information received from the digital broadcast receiver 5 that has been successfully authenticated is registered. The authentication registration broadcast device 14 can maintain the credibility of the safety information by broadcasting the safety information received from the digital broadcast receiver 5 that has been successfully authenticated.

  As described above, the information collection system of FIG. 1 broadcasts as a data broadcast so that the safety information registration screen 7 can be displayed only by the digital broadcast receiver 5 installed in the refuge 4, and receives the digital broadcast that has been successfully authenticated. By registering only the safety information received from the machine 5, it is possible to eliminate the risk of registering safety information by impersonating a victim other than the disaster victim.

  FIG. 2 is a hardware configuration diagram of an example of the information collection apparatus. 2 includes an input device 21, an output device 22, a drive device 23, an auxiliary storage device 24, a memory device 25, an arithmetic processing device 26, and an interface device 27 that are mutually connected by a bus B. The

  The input device 21 includes a keyboard and a mouse, and is used for inputting various signals. The output device 22 includes a display device and is used to display various windows, data, and the like. The interface device 27 includes a modem, a LAN card, and the like, and is used for connecting to the network 3.

  The information collection program is at least a part of various programs that control the information collection apparatus 1. The information collection program is provided by, for example, distribution of the recording medium 28 or downloading from the network 3. The recording medium 28 on which the information collecting program is recorded is information such as a CD-ROM, a flexible disk, a magneto-optical disk, etc., a recording medium for recording information optically, electrically or magnetically, a ROM, a flash memory, etc. Various types of recording media, such as a semiconductor memory that electrically records data, can be used.

  When the recording medium 28 on which the information collection program is recorded is set in the drive device 23, the information collection program is installed from the recording medium 28 to the auxiliary storage device 24 via the drive device 23. The information collection program downloaded from the network 3 is installed in the auxiliary storage device 24 via the interface device 27. The information collection device 1 stores the installed information collection program and also stores necessary files, data, and the like.

  The memory device 25 reads and stores the information collection program from the auxiliary storage device 24 at startup. The arithmetic processing unit 26 implements various processing blocks as will be described later in accordance with the information collection program stored in the memory device 25. In the hardware configuration diagram of FIG. 2, illustration of broadcasting facilities for performing television broadcasting, radio broadcasting, and data broadcasting is omitted.

  FIG. 3 is a processing block diagram of an example of a digital broadcast receiver. The digital broadcast receiver 5 of FIG. 3 includes a tuner unit 31, a descrambler 32, a TS decoding unit 33, a video / audio decoding unit 34, a telephone modem 35, a control unit 36, a display unit 37, and a key input unit 38. . A B-CAS card 39 is inserted in the digital broadcast receiver 5.

  The input broadcast signal is supplied to the TS decoding unit 33 via the tuner unit 31 and the descrambler 32. The TS decoding unit 33 demultiplexes the broadcast signal into a video signal, an audio signal, and data broadcast content. The demultiplexed data broadcast content is supplied to the control unit 36.

  The control unit 36 reads the program “startup.bml” that is to be accessed first in the data broadcast content from the supplied data broadcast content. In the program “startup.bml”, for example, an operation of “reading the program main body“ anpi.bml ”of the safety registration content when the red button is pressed for a long time without displaying anything on the screen” is described.

  For example, when the red button of the remote controller 40 is pressed for a long time, the control unit 36 reads the program main body “anpi.bml” of the safety registration content. The program body “anpi.bml” of the safety registration content has, for example, an operation of “obtaining the B-CAS number of the digital broadcast receiver 5 and displaying the safety information registration screen 7 on the display device 6 if necessary”. Describe it.

  The control unit 36 acquires a B-CAS number from the B-CAS card 39. If the acquired B-CAS number is included in the file (bcas.btb) representing the B-CAS number to be displayed on the safety information registration screen 7, the control unit 36 displays the safety information registration screen 7 on the screen. Is displayed. The control unit 36 can monitor and output the safety information registration screen 7 by controlling the display unit 37.

  The disaster victim operates the remote controller 40 to register the safety information on the safety information registration screen 7 displayed on the display device 6 by the monitor output. The control unit 36 transmits an arbitrary area of NVRAM (nonvolatile ROM) which is a non-volatile memory (not shown) of the own device before transmitting the registered safety information and the B-CAS number of the own device to the information collecting apparatus 1. If the transmitted flag is not stored in, since it is the first transmission, the transmitted flag is set. Then, the control unit 36 uses the telephone modem 35 to transmit the registered safety information and its own B-CAS number to the authentication registration broadcasting device 14 of the information collecting device 1 via the network 3.

  In addition, before transmitting the safety information registered and the B-CAS number of the own device to the information collecting apparatus 1, the control unit 36 arbitrarily selects NVRAM (nonvolatile ROM) which is a non-volatile memory (not shown) of the own device. If the transmitted flag is stored in this area, since it is the second and subsequent transmissions, the transmitted flag is read. Then, the control unit 36 uses the telephone modem 35 to transmit the registered safety information, its own B-CAS number, and the read transmission flag to the authentication registration broadcasting device 14 of the information collecting device 1 via the network 3. .

  FIG. 4 is a processing block diagram of an example of the authentication registration broadcasting apparatus. The authentication registration broadcasting device 14 in FIG. 4 includes an authentication unit 51, a safety information registration unit 52, and a broadcasting unit 53. When the authentication unit 51 receives the registered safety information and the B-CAS number of the digital broadcast receiver 5 via the network 3, the authentication unit 51 determines that it is the first transmission and stores it in its own hard disk (not shown). It is confirmed that the received B-CAS number is not registered in the authenticated list.

  If it can be confirmed that the received B-CAS number does not exist in the authenticated list stored in the hard disk (not shown) of the own device, the authentication unit 51 registers the B-CAS number and determines that the authentication is successful. If it is confirmed that the received B-CAS number exists in the authenticated list stored in the hard disk (not shown) of the own device, the authentication unit 51 determines that the authentication has failed.

  Further, when the authentication unit 51 receives the registered safety information, the B-CAS number of the digital broadcast receiver 5 and the transmitted flag via the network 3, the authentication unit 51 determines that the transmission is the second or later transmission, and the hard disk of its own device. It is confirmed that the received B-CAS number exists in the authenticated list stored in (not shown).

  If it can be confirmed that the received list stored in the hard disk (not shown) of the own apparatus has the received B-CAS number, the authentication unit 51 determines that the authentication is successful. If it is confirmed that there is no received B-CAS number in the authenticated list stored in the hard disk (not shown) of the own device, the authentication unit 51 determines that the authentication has failed.

  According to the authentication of the authentication unit 51 as described above, for example, when the B-CAS card 39 is stolen after the first transmission and the B-CAS card 39 is inserted into another digital broadcast receiver 5 and used, Safety information from the digital broadcast receiver 5 can be repelled without being registered.

  Specifically, the other digital broadcast receiver 5 does not have a transmission completion flag, and determines that the transmission is the first transmission, and the registered safety information and the B-CAS number of the own device are transmitted via the network 3 to the information collection device 1. To the authentication unit 51. When the authentication unit 51 receives the registered safety information and the B-CAS number of the digital broadcast receiver 5 via the network 3, the authentication unit 51 determines that it is the first transmission and stores it in its own hard disk (not shown). Confirm that the received B-CAS number is not in the authenticated list. However, the authentication unit 51 determines that the authentication has failed because the received B-CAS number is included in the authenticated list stored in its own hard disk (not shown). That is, the authentication unit 51 can estimate that the B-CAS card has been stolen.

  If the B-CAS card 39 is stolen before the first transmission, the B-CAS number of the B-CAS card 39 is displayed on the safety information registration screen 7 stored in the B-CAS number DB 12. What is necessary is just to delete from the target B-CAS number.

  The safety information registration unit 52 registers the safety information from the digital broadcast receiver 5 that has been successfully authenticated. The broadcast unit 53 broadcasts the registered safety information on a television program, a radio program, a data broadcast, a homepage, or the like.

  The B-CAS number to be displayed on the safety information registration screen 7 stored in the B-CAS number DB 12 may be registered in advance as a B-CAS number used in the refuge 4. Then, the B-CAS number of the digital broadcast receiver 5 installed in the refuge 4 may be registered.

  In the information collection system of FIG. 1, when the disaster information is collected at the broadcasting station in the event of a disaster, the safety information registration screen 7 can be displayed on the digital broadcast receiver 5 installed in the evacuation site 4, By broadcasting as a data broadcast so that it can not be displayed on the digital broadcast receiver 5 installed other than 4, it eliminates the risk of non-disaster victims impersonating victims and registering safety information and minimizing the occurrence of mischief be able to.

  In addition, the information collection system of FIG. 1 can eliminate the risk of registering safety information by impersonating a victim other than the victim due to theft of the B-CAS card and minimizing the occurrence of mischief. As a result, the information collection system of FIG. 1 can efficiently collect highly reliable safety information.

  FIG. 5 is a configuration diagram of another example of the information collection system of the present invention. In the information collection system of FIG. 5, an information collection device 1 and a digital broadcast receiver 5 are connected via a network 3 such as the Internet network. The digital broadcast receiver 5 can receive data broadcasts and can use interactive services.

  The information collection device 1 includes an authentication content generation device 61, a program DB 11, a B-CAS number DB 12, a data broadcasting device 13, and an authentication registration broadcasting device 14. In the information collection system of FIG. 5, the information collection device 1 including one case is described as an example, but the authentication content generation device 61, the program DB 11, the B-CAS number DB 12, the data broadcasting device 13, and the authentication A part or all of the registered broadcasting device 14 may be installed in separate housings.

  The authentication content generation device 61 distinguishes between a past disaster and a program body of authentication content read from the program DB 11, a file representing a B-CAS number to be displayed on the authentication screen read from the B-CAS number DB 12, and past disasters. Authentication content is created with a specific disaster number.

  The program body of the authentication content is described in, for example, a broadcast markup language. It is assumed that the B-CAS number of the digital broadcast receiver 5 installed in the refuge 4 is registered in the B-CAS number DB 12 as the B-CAS number to be displayed on the authentication screen. In addition, it is assumed that a disaster number is registered in the authentication content generation device 61.

  The authentication content created by the authentication content generation device 61 is transmitted to the data broadcasting device 13. The data broadcasting device 13 broadcasts the authentication content as data broadcasting content. The digital broadcast receiver 5 installed in the evacuation center 4 receives the data broadcast from the data broadcast device 13 via the data broadcast network 2 and displays an authentication screen on the display device 6.

  At this time, in order to suppress the occurrence of mischief, the information collection system of FIG. 5 uses the B-CAS number so that the digital broadcast receiver 5 installed in the shelter 4 can display the authentication screen. The digital broadcast receiver 5 installed in the system cannot display the authentication screen.

  In the information collection system of FIG. 5, for example, the B-CAS number of the digital broadcast receiver 5 that can display an authentication screen is broadcast as a data broadcast together with the program body of the authentication content. Thus, the authentication screen can be displayed and the digital broadcast receiver 5 installed outside the refuge 4 can be prevented from displaying the authentication screen.

  The victim uses the information input function of the digital broadcast receiver 5 and inputs the password from the authentication screen displayed on the display device 6. The digital broadcast receiver 5 uses the communication function of its own device, and transmits the input password and its own B-CAS number to the authentication registration broadcasting device 14 of the information collecting device 1 via the network 3.

  The authentication registration broadcasting device 14 performs password authentication and transmits the authentication result to the digital broadcast receiver 5 via the network 3. If the authentication is successful, the digital broadcast receiver 5 stores the authentication success flag and the disaster number in NVRAM, which is a non-volatile memory (not shown) of the digital broadcast receiver 5.

  The digital broadcast receiver 5 transmits the B-CAS number to the authentication registration broadcast device 14 of the information collection device 1 via the network 3. The authentication registration broadcasting device 14 reads the initial setting content from the program DB 11 and transmits the initial setting content to the digital broadcast receiver 5 via the network 3. The initial setting content is not received via the data broadcast network 2 but is received via the network 3 and is therefore called communication content.

  The digital broadcast receiver 5 displays an initial setting screen on the display device 6 based on the received initial setting content. The disaster victim uses the information input function of the digital broadcast receiver 5 to input initial setting information such as a shelter name from the initial setting screen displayed on the display device 6. The digital broadcast receiver 5 transmits the input initial setting information to the authentication registration broadcast device 14 of the information collection device 1 via the network 3 using the communication function of the own device. The authentication registration broadcast device 14 registers the initial setting information in association with the received B-CAS number of the digital broadcast receiver 5.

  Further, the digital broadcast receiver 5 transmits the B-CAS number again to the authentication registration broadcast device 14 of the information collection device 1 via the network 3. The authentication registration broadcasting device 14 reads the safety registration content from the program DB 11 and transmits the safety registration content to the digital broadcast receiver 5 via the network 3. The safety registration content is not received via the data broadcasting network 2 but is received via the network 3 and is therefore called communication content.

  The digital broadcast receiver 5 displays a safety information registration screen on the display device 6 based on the received safety registration content. The victim uses the information input function of the digital broadcast receiver 5 and inputs safety information such as name, zip code, address, and comment from the safety information registration screen displayed on the display device 6. The digital broadcast receiver 5 transmits the input safety information to the authentication registration broadcast device 14 of the information collection device 1 via the network 3 by using its own communication function. The authentication registration broadcast device 14 registers the safety information in association with the received B-CAS number of the digital broadcast receiver 5.

  Based on the B-CAS number, the authentication registration broadcasting device 14 combines initial setting information such as a refuge name and safety information such as a name, a postal code, an address, and a comment registered by a disaster victim, thereby creating a television program or radio. Broadcast on broadcasting facilities such as programs, data broadcasting, and homepages.

  The authentication registration broadcasting device 14 can maintain the credibility of the safety information by broadcasting the initial setting information received from the digital broadcast receiver 5 that has been successfully authenticated and the safety information.

  As described above, the information collection system in FIG. 1 broadcasts as a data broadcast so that the authentication screen can be displayed only by the digital broadcast receiver 5 installed in the evacuation shelter 4, and from the digital broadcast receiver 5 that has been successfully authenticated. By registering the received initial setting information and safety information in combination, it is possible to eliminate the risk of registering safety information by impersonating a disaster victim.

  The hardware configuration of the information collection device 1 in FIG. 5 is the same as that in FIG. The hardware configuration of the digital broadcast receiver 5 of FIG. 5 is the same as that of FIG.

  The input broadcast signal is supplied to the TS decoding unit 33 via the tuner unit 31 and the descrambler 32. The TS decoding unit 33 demultiplexes the broadcast signal into a video signal, an audio signal, and data broadcast content. The demultiplexed data broadcast content is supplied to the control unit 36.

  The control unit 36 reads the program “startup.bml” that is to be accessed first in the data broadcast content from the supplied data broadcast content. In the program “startup.bml”, for example, an operation of “nothing is displayed on the screen and the main body of the authentication content is read when the red button is pressed for a long time” is described.

  For example, when the red button of the remote controller 40 is pressed and held, the control unit 36 reads the program body of the authentication content. In the authentication content program body, for example, an operation of “obtaining the B-CAS number of the digital broadcast receiver 5 and displaying an authentication screen on the display device 6 if necessary” is described.

  The control unit 36 acquires a B-CAS number from the B-CAS card 39. If the acquired B-CAS number is included in the file representing the B-CAS number to be displayed on the authentication screen, the control unit 36 displays the authentication screen on the screen. The control unit 36 can monitor and output the authentication screen by controlling the display unit 37.

  The victim operates the remote controller 40 to input the password to the authentication screen displayed on the display device 6. The control unit 36 uses the telephone modem 35 to transmit the input password and its own B-CAS number to the authentication registration broadcasting device 14 of the information collecting device 1 via the network 3.

  The control unit 36 uses the telephone modem 35 to receive the authentication result from the authentication registration broadcasting device 14 of the information collecting device 1. When the authentication is successful, the control unit 36 stores the authentication success flag and the disaster number in NVRAM which is a non-volatile memory (not shown) of the own device.

  Subsequently, the control unit 36 uses the telephone modem 35 to transmit its own B-CAS number to the authentication registration broadcasting device 14 of the information collecting device 1 via the network 3. The control unit 36 uses the telephone modem 35 to receive the initial setting content from the authentication registration broadcasting device 14 of the information collecting device 1. The control unit 36 outputs an initial setting screen to the display device 6 based on the received initial setting content.

  The disaster victim inputs initial setting information such as a shelter name by operating the remote controller 40 on the initial setting screen displayed on the display device 6. The control unit 36 uses the telephone modem 35 to transmit the input initial setting information and its own B-CAS number to the authentication registration broadcasting device 14 of the information collecting device 1 via the network 3.

  The control unit 36 uses the telephone modem 35 to receive the safety registration content from the authentication registration broadcasting device 14 of the information collecting device 1. The controller 36 monitors and outputs a safety information registration screen to the display device 6 based on the received safety registration content.

  The disaster victim inputs safety information such as a name, a postal code, an address, and a comment to the safety information registration screen displayed on the display device 6 by operating the remote controller 40. The control unit 36 uses the telephone modem 35 to transmit the input safety information and its own B-CAS number to the authentication registration broadcasting device 14 of the information collecting device 1 via the network 3.

  When the channel for channeling safety information is selected again after the channel is changed or the power is turned off and the red button is pressed for a long time, the control unit 36 stores the authentication success flag and the disaster number in its own NVRAM. If the valid authentication success flag and the disaster number are stored in the NVRAM of the own device, it is determined that the authentication has been completed. If authenticated, the control unit 36 receives the safety registration content from the authentication registration broadcasting device 14 of the information collecting device 1, and outputs a safety information registration screen to the display device 6 based on the safety registration content.

  FIG. 6 is a processing block diagram of an example of the authentication registration broadcasting apparatus. The authentication registration broadcasting device 14 of FIG. 6 includes an authentication unit 71, a communication content transmission unit 72, an initial setting information registration unit 73, a safety information registration unit 74, and a broadcasting unit 75.

  When the password and the B-CAS number of the digital broadcast receiver 5 are received via the network 3, the authentication unit 71 performs password authentication and transmits the authentication result to the digital broadcast receiver 5 via the network 3.

  When the B-CAS number of the digital broadcast receiver 5 is received via the network 3, the communication content transmitting unit 72 reads the initial setting content or the safety registration content from the program DB 11, and stores the initial setting content or the safety registration content in the network 3. Via the digital broadcast receiver 5.

  When initial setting information such as a shelter name and the B-CAS number of the digital broadcast receiver 5 are received via the network 3, the initial setting information registration unit 73 associates with the received B-CAS number of the digital broadcast receiver 5. To register the initial setting information.

  When the safety information such as name, zip code, address, and comment and the B-CAS number of the digital broadcast receiver 5 are received via the network 3, the safety information registration unit 74 receives the B-CAS of the received digital broadcast receiver 5. The safety information is registered in association with the number.

  The safety information registration unit 74 further combines the initial setting information such as the name of the refuge with the safety information such as the name, zip code, address, and comments registered by the victim based on the B-CAS number, 75. The broadcasting unit 75 broadcasts the initial setting information and the safety information combined based on the B-CAS number using broadcasting facilities such as a television program, a radio program, a data broadcast, and a homepage.

  In the information collection system of FIG. 1, when disaster information is collected at a broadcasting station in the event of a disaster, an authentication screen can be displayed on the digital broadcast receiver 5 installed in the evacuation center 4. By broadcasting as a data broadcast so that it cannot be displayed on the installed digital broadcast receiver 5, the risk of registering safety information by impersonating a victim other than the victim can be eliminated, and the occurrence of mischief can be minimized. .

  In addition, the information collection system of FIG. 1 can eliminate the risk of registering safety information by impersonating a victim other than the victim due to theft of the B-CAS card and minimizing the occurrence of mischief. Specifically, it is possible to cope with theft of the B-CAS card by not permitting authentication from the same B-CAS number at the time of authentication.
